I've certainly flown in and out of Wattisham in a VC10! Although it is a bit tight east of the old Q access, for sure.
We also used to be able to bring back as many folks as we could squeeze in to the VC10K when we were trailing jets home from APC etc - because we were under the OpCon of the AAR people at Gp, not the leaden hand of Ascot Ops who ran the shiny fleet.
So we took peeps to Leeming (div to Tesside due to cross winds), Marham, Wittering, Leuchars etc whenever we could. BUT that was also because the aircraft and crew weren't subject to DTMA tasking - and because we could!
Having been on the other side of the fence myself and enjoyed waiting for a coach trip from Brize to Suffolk, I was always keen to try to fly the guys direct to their own bases if chums at Gp could be persuaded.
With crew manning and tasking being the way I'm told it is these days, the necessary slack in the system just isn't there to provide door-to-door trooping, very regrettably.
